VENDING MACHINE WITH SPURIOUS- COIN DETECTOR.

Application filed December 7, 1921. Serial No. 520,682.

To all whom it may concern.

Be it known that I, DANIEL L. CHANDLER, a citizen, of the United States, residing at Fitchbur in the county of Worcester and State ofmassachusetts, have invented new and useful Improvements in Vending Machines with Spurious-Coin Detectors, of which the following is a specification This invention relates to a machine for vending articles and is of a character in which manually operable mechanism is provided which is rendered operable by means of a coin inserted in the casing of the ma- .chine.

The object of the invention is to provide a simple and effective slot machine for vending articles which will operate only when a coin of predetermined dimensions is deposited therein to deliver one of the articles to theparty depositing the coin, but which, in the event that there are none of such articles in the machine, or in the event that any of said articles are not of a predetermined size, will eject the coin from the machine so that the party who has deposited the coin may obtain possession thereof. In the event that the article or articles are of the proper dimensions, thecoin will be i etained by the n'iachinc and the article delivered to the de posizor of the coin. If, however, the coin is a spurious coin, or what is known as a blank, the dimensions of which are not the same as the coin which it is planned shall operate the machine, then the article is not delivered to the party operating the machine-and the spurious coin is ejected therefrom. The

same would be true of any coin whether spurious or not which was of different dimensions from that intended and designed to be used in the machine of this invention. For example, if the machine is designed, as in the present embodiment of my invention, to use a nickel or five cent piece, then it a penny or a dime should be inserted in the machine, the mechanism would not be rendered operative to deliver one of the articles, but would be operative to eject the ten cent 7 piece or the penny from the machine.

The machine of this invention also has an attachment for operating an advertising device which will display a different card or plurality of cards each time the machine is operated.

The mechanism of this invention is all mounted upon the underside of a plate constituting the top of the casing of the machine for convenience in manufacture and repairs.

In the device of this invention the article which is to be vcnded if it is of a predetermined size renders the mechanism for ejecting the coin from the machine inoperable for that purpose and the coin is deposited in a receptacle provided for that purpose in the machine, but when the articles are exhausted from the machine, or if for any reason they do not feed to the delivery mechanism so as to be ejected from the machine, then the mechanism for ejecting the coin from the machine becomes operative. If no coin is placed in the machine, then-the manipulation of the crank whereby the article is ejected from the machine and the coin deposited in the coin receptacle becomes inop erative. i

The invention consists in a machine of the character set forth of mechanism which only upon the deposit of a coin in the machine of predetermined dimensions is operable to eject the coin from the machine when the article to be vended is not ejected therefrom,

or when the article which is ejected there- Fig. 2 is an underneath plan of the same.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is the casing of the machine and 11 the top of said casing which is rigidly and detachaoly fastened to the casing and has mounted thereon upon the underside the coin controlling, coin detecting and article feeding mechanisms. and upon the upper side, the magazine 12 for holding the articles to be fed and also the movable advertising device 13. The mags-- zine consists, in the present embodiment of my invention, of a rectangular metal container 14 which is fastened to the top 11. The container is provided with a 'slidable glass front 15, the upper end of which is locked by a padlock 16 to the upper end of the container. The lower end of the slide 15 engages a notch 1? formed in the upper edge of an arm 18 which extends horizontally along the upper face of thetop 11 and thence projects/downwardly in the form of a vertical rod 19 and ough a receptacle 20 for the coin and into the base 21 upon which the casing 10 is fastened. The rod 19, together with the arm 18, thus act as a lock to prevent the coin receptacle 20 from being withdrawn from the machine by unauthorized persons. A guide member 22 is provided at the rear of the base of the magazine and it is slidahly mounted in the top of the casing. This guide member is held in the position illustrated in Fig. 5 when the parts are not being operated, by the rear end of a carrier slide 23 which is slidably mounted on the underside of the topll and abuts against a downwardly projecting flange 24 on the guide member 22. Said guide member is also provided on its front edge with a vertical flange 25 which projects downwardly in the rear of the article 26 in a column of articles 27, this being the next to the lowermost article in the column of articles so that when the lowermost article 28 of said column of articles is moved forward by the carrier slide 23 as hereinafter described, the article 26 will drop downwardly into the place formerly occupied by the article 28 when the carrier slide has returned to its normal position, and the article 26 will be prevented from tipping or, in other words, it

will be guided to enter the space 29 provided in the carrier slide 23 by the flange 25 of the guide member 22 which will be pressed against said article 26 by means of springs 30 which bear against the flange 25 and act to ca ry the guide member 22 forwardly and against the article 26 as soon as the carrier slide 23 has moved forward a slight distance. The carrier slide 23 is arranged to slide in ways 31 formed upon the underside of the top 11 and a reciprocatory motion is imparted to said slide to feed the article from the magazine 12 out of the machine by a rod 32 which is slidably mounted in a bearing 33 forming a part of the carrier slide 23. The front end of the rod 32 is provided with a head 34 which has a vcrti cal slot 35 therein in which is slidably located a crank pin 36 fastened to a crank 37 on a shaft 38. The crank shaft 38 is rotatably mounted in bearings 39 and 40 fast to the underside of the-top 11 and is prevented from moving longitudinally thereof by said crank and by a collar 41 fast thereto and contacting with the end of the bearing 40. The collar 41 has one end of a spring 42 attached thereto by means of a screw 43, the other end of the spring being attached to the top 11 by a screw 44. crank handle is fastened to the outer end of the shaft. 38 so that by rotating the crank shaft 38 by means of the crank handle 45 a reciprocatory mo tion will be imparted to the rod 32 hy the crank pin 36. -The spring 42 acts to rotate the shaft 38 in the direction of the arrow a. Fig. 2, and a pin 46 strikes against the upper surface of the top and limits the distance to which the crank shaft 38 can he rotated by the spring The rod 32 is locked tothe carrier slide 23 hy a coin 4? when it is dropped into ti machine in the following manner :The rain 47 dropped downwardly through a slot 48 formed the top 11. which when the parts are in their normal position. aligns with a slot in the carrier slide 23 as illustra ed in Figs. I"; and 4. The coin 47 when dropped into the slot 48 descends into the slot 49 in the can rier slide and upon a finger fell as illustrated in Fig. 3. The stop finger is pivoted at 51, Fig. 2, to the carrier slide 23, and is adapted to alternately engage cars 52 and 53 on a stop plate 54 which is fast to the top 11 whereby the lever or stop finger 50 will be moved to close the lower end of the passage 49 and hold the coin 47 therein, or will be moved to open the lower end of said passage 49 and allow the coin to pass downwardly and out. of said passage. When the coin 47 is in the position illustrated in Figs. 3 and 4, it projects into a notch 55 provided in the actuating member or rod 32, and when in that position, lies between the adjacent ends of two oppositely disposed hardened screws 56 and 67 which have screwthreaded engagement with the carrier slide 23 and have fastened to their outer ends a pair of arms 58 and 59 respectively. The arm 58 has a pin 60 fast thereto which projects through a hole in the arm 59 and is slidable therein, and the arm 58 is provided with a projection 62 to which is pivotally connected at 63 a link 64 which is slotted at 65 to receive the free end of a lever 66 which projects through said slot and is pivoted at 67 to the carrier slide 23, the

opposite end of said lever 66 being provided with a vertical pin 68 which projects into a cam slot 69 provided in a cam plate 70 fast to a bracket 71 which, in turn, is fastened to the top 11 and is, at all times in the op eration of the machine, stationary. The lever 66 ,is connected by a spring 72 to the link 64. The arms 58 and'59 are split to receive their respective screws 56 and 57 and these screws are rigidly fastened to their respective arms by clamp screws 73 as illustrated in Figs. 3 and 4, so that the adjacent ends of the screws 56 and 57 may be adjusted toward or away from each other and clamped in adjusted position. The radial in 61 on the arm 58 projects into an orifice 4 provided in a cam plate 75 form ing a part of a slide 76 moimted to slide in ways 77 on a bracket 78 fast to the top 11. This slide has fast thereto an auxiliary coin chute 79 which has two vertical passages 80 and 81 provided therein. The passage 80 guides the coin to a coin receptacle 8-2 and the passage 81 guides the coin into a chute 83, Fig. 5, which empties onto a shelf 84 on the front of the machine and outside the casing 10. The auxiliary chute is positioned with the passage 80 in line with the coin slot 49 when there is an article of the proper size about to be delivered from the machine and also said passage 80 is in alignment with the coin slot 49 when the coin which is to be delivered is of the regulation predetermined dimensions, and the passage 81 is moved into alignment with the coin slot 49 when there is no article delivered from the machine, or when the coin which is put into the machine is not of the regulation predetermined dimensions. To accomplish this result the auxiliary chute is moved longitudinally relatively to the carrier slide 23 to bring the passage 80 into alignment with the lower end of the coin slot 49, or the passage 81 into alignment with said coin slot and this is accomplished in the following manner: If a regulation coin, in the present instance a five cent piece or nickel, is dropped into the machine, the carrier slide 23, as hereinbefore described, will be locked to the rod 32, then uponthe crank handle 45 being operated by moving it over toward the front of the machine, the carrier slide 23 and the rod 32 will move together as one piece, and the arms 58 and 59 will be rocked downwardly, Fig. 2, by the link 64, spring 72, lever 66, pin 68 and cam late 70, the action being as follows 1611 the carrier slide 23 is moved forwardly as hereinbefore described the pin 68 will travel with it toward the front of the machine, see Fig. 2, and will move in the cam slot 69, rocking the lever 66, the end of which projects through the slot 65 in the link 64, and by the spring 72 the link. 64 will be drawn toward the right, Fig. 2, thus tipping the arm 58 and its radially extending pin 61 downwardly in said figure and at the same time tipping the arm 59 downwardly, the two being slidably connected relatively to each other by the pin 60. This will cause the screws 56 and 57 which are respectively left and right-handed screws, to approach and grip the coin 47 with a positively applied yielding pressure. If the coin is of predetermined size, in other words, a regulation standard coin, such as a nickel in the present instance, thearms 58 and 59 will tip downwardly to a sufficient extent so that the radial pin 61 will pass along the orifice 74, see Fig. 11, in the direction of the arrow Z). The pm 61 will clear a tooth 85 and will pass beneath said tooth and above a shoulder 86 forming a portion of the lower edge of said orifice. Thus the slide 76 to which the coin chutes 80 and 81 are attached will remain stationary and when the carrier slide has arrived at its extreme forward position, the coin will be released by the action of the lever 66 which being operated by the pin 68 is moved to cause the end which projects into the slot 65 to move toward the left, Fig. 3, thus eventually abutting against the left hand end of the slot65 and through the link 64 causing the arms 58 and 59 to be moved upwardly and the screws 56 and 57 to move away from each .other, thus releasing the coin which will drop into the chute 80 and be delivered into the receptacle 20, then when the handle 45 is released, the spring 42 will &

If instead of the coin being a standard coin of predetermined dimensions it is thicker than the standard dimensions, it is evident that upon the machine being operated as hereinbefore described, the arms 58 and 59 could not move downwardly as far as in the case where a thinner standard coin Was in use. In such a case the ends of the screws 56 and 57 would abut against the spurious coin before the radial pin 61 had moved downwardly to a suliicient ex tent to clear the tooth 85 so that said pin 61 would engage the tooth 85 and move the slide 76 and the auxiliary coin chute 79 thereon so that when the arms 58 and 59 were operated at the end of the forward movement of the carrier slide to move upwardly and release the spurious coin, it would drop into the chute 81 and from thence would pass onto the chute 83 and out onto the shelf 84:.

if instead of a standard coin being used a coin thinner than the standard coin were placed in the machine, but of substantially the same diameter, the parts would operate as hereinbefore described, except that in this case the arms- 58 and 59 would be tipped downwardly to a greater extent than in either of the prior cases, that is, to a greater extent than would be the case where a standard coin was employed, and in the case the radial pin 61 would move downwardly into alignment with the shoulder 86 on the cam plate 75 and thus again upon further forward movement of the carrier slide, the slide 7 6 would be moved forwardly together with the auxiliary coin chute 79 and the coin would be dropped as hereinbefore described and fall into the chute 81, thence passing onto the chute 83 and out of themachine onto the shelf 84.

. If the coin which is dropped into the machine is of a smaller diameter than a five cent piece and is thinner than a five cent piece, as, for example, a dime, then the coin would not project into the notch 55 in the rod 32 and, therefore, the rod 32 and the carrier slide would not be locked together. In a case of this sort when the crank handle 45 is operated, the rod 32 will move forwardly and the carrier slide 23 will remain stationary and when the rod has been brought to its extreme -forward position in this manner, the stop finger 50 will be engaged by an arm 87, see Fig. 9, which is provided on a bracket 88 fast to the head 34. lfhis arm 87 as the rod 32 is moved forwardly as hereinbefore described, enters a slot 89 in the carrier slide 23 and engages the stop finger 50 moving it on its pivot 51 and thus allowing the coin or blank to drop out of the coin slot 49, and into the coin chute 81, see Fig. 5,-which will allow the coin to pass downwardly onto the chute 83 and out onto the shelf 84: returning the same to the operator of the machine.

Article feeding mechanism.

.mains stationary therefore when the auxiliary coin chute is stationary, the auxiliary coin chute moves when a spurious coin or blank is inserted in the machine, and therefore, no article is delivered from the machine under such circumstances. Ween, however, a coin of standard size is placed in the machine as hereinbeiore described the coin chute will remain stationary and the article will be carried forward by the carrier slide until it has passed beyond the plate 90 whereupon it drops out of the carrier slide and down onto a stationary. shelf 106 as shown. in dotted lines, Fig. 5. The carrier slide has depending therefrom a pusher 107 which is rigidly fastened thereto and when this pusher returns with the carrier slide to its normal position, it will push the article 28 off of the shelf-106 whereupon said article will drop onto the chute 83 and be delivered to the shelf 84 on the outside and at the front of the casing. A. feeler finger 92, see Figs. 2, 6 and 8, is pivoted at 93 to the carrier slide 23 and has an arm 9d at its free end which projects throu h a slot 95 in the carrier slide 23 and as a spring 96 connected thereto. "When the parts are in the relative positions illustrated in Fig. 2 the extreme free end of the arm 94 is out of engagement with the lowermost article 28 in the column of articles 27 so that said lowermost article is free to drop onto the plate 90 when the carrier slide returns to its normal position. Thefeeler finger 92 has an upwardly rojecting pin 97 fast thereto which pro ects into an orifice 98 in a cam plate 99 which is stationary and is adjustably fastened by screws 100 to the top 11. As illustrated in Fig. 7 the pin 97 bears against the edge 101 of the cam plate 99 and in this position the free end 94 of the feeler finger is held out of engagement with the article which rests upon the plate 90. lVhen the carrier slide is moved forward as hereinbefore described and there is a standard coin in the machine locking the carrier slide to the rod 32, then the pin 97 will move in the direc: tion of the arrow 0, Fig. 7, until it leaves the edge 101 whereupon the feeler finger will be moved by the spring 98 until its free end engages the article 28. further movement forward of the carrier slide and as the article is being pushed ofi Upon a of the plate 90the pin 97 will engage the cam edge 102 and the feeler finger 92 will then be rocked to carry its free end away from and out of engagement with the article 28, thus releasing the article 28 and leaving it free to be pushed off of the plate 90 and to fall onto the chute 83 tobe guided thereby downwardly and out of the machine onto the shelf 84. At the same time a projection 103 on the feeler finger 92 will be moved out of alignment with an ear 104 which projects laterally from the extension 91 on the auxiliary coin chute slide. When the carrier slide is released and allowed to return to its normal position, the machine is ready for another'operation.

Assuming now that a spurious coin of dimensions difierent from that of the standard coin is introduced into the machine, then upon a movement forward of the carrier. slide, the spurious coinwill be returned to the operator as hereinbefore described and the auxiliary coin chute slide 76. to

gether with the extension 91 and the plate 90 fast to said extension will move with the carrier slide and the plate 90 will remain under the article 28 and the article will return to its previous position at the bottom of the column of articles,.but will 'not be delivered from the machine.

In the event that there is no article to be fed by the carrier slide for any reason whether because there are no articles left in the magazine or because theynfail to feed downwardly until the lowermost article is deposited in the carrier slide, then the feeler finger 92 will be moved by the spring 96 inwardly until the pin 97 passes into the position illustrated in dotted lines, Fig. 7, and upon a further forward movement of the carrier slide the pin 97 ,will pass along the edge 105 of the cam plate 99. This will bring the projection 103 on the feeler finger into alignment with the lateral projection 104 on the extension 101 of the'auxiliary coin chute slide and upon further forward movement of the carrier slide, said projection 103 will abut the projection 104 and move the auxiliary coin chute so that when the slide is in its extremeforward position and the coin is dropped, it will drop intothe chute 81 and pass down the chute83 onto the shelf 84 thus returning the money to the user of the machine when he does not receive the article which he has'paid for. The same would be true if the, article were smaller than standard size for in that case the feeler finger would be allowed to project into the position where the projection 97 is in the position illustrated in dotted lines, Fig. 7.

The advertising device is substantially the same as that described and illustrated in application filed by me on September 17,

' 1921 entitled Vending machine with return coin mechanism, Serial No. 501,476 and consists of a cylinder 108 rotatably mounted upon the top 11 and within a stationary cylinder 109 fast to the top 11 andprovided with a ver-- tical' opening 110 through which advertising cards on the cylinder 108 can be seen -.as said cylinder is rotated step by step as hereinafter described and consisting of a shaft 111 fast to said cylinder 108 and projecting downwardly through the top 11. The said shaft is rotated by a link 112 connected at one end thereof to the carrier slide 23 and at the other end thereof to a pawl carrier 113, said pawl carrier being pivotally mounted upon the shaft 111 and having a feed pawl 114 mounted thereon and adapted to engage a toothed ratchet 115 for the purpose of imparting an intermittent rotary motion to said toothed ratchet which being fastened to the shaft 111, will cause said shaft to rotate in the direction of the arrow (1, Fig. 2. The shaft 111 is prevented from rotating in a direction reverse to that of the arrow (Z by a locking pawl 116.

\Vhen a coin has-been deposited in the machine, as illustrated in .dotted lines in Fig. 3, and 'in full lines in Fig. 5, and it rests in the posit-ion therein shown, and the operator moves the crank handle to bring the-slide 23 forwardly, it is desirable that the slide should be caused to make its full, forward movement before it can return to its rearward position illustrated in Fig. 2, and this desirable result is secured by means described and .illustrated by me in said application for Letters Patent and consists of a latch 117 which is pivoted at 118 to the cover 11 and is provided on its under edge with teeth 119 and with an inclined forward portion 120. The latch 117 is held downwardly against a stop screw 121 by a spring 122. It'will be seen that the operation of this locking latch is as follows :-When the slide 23 is moved forwardly, the upper edge of the coin 47 will engage the inclined edge 120 and will lift the latch 117 slightly, and upon further forward movement of the carrier slide, the edge of the coinwill be engaged by the different teeth'119 which are so shaped as to prevent the slide from returning as long as there is a coin 47 located in the coin slot 49'. Upon arriving at its forward position, however, the coin will be pushed down and out of the slot 49 by the action of the spring 122 and the latch 117, thereupon the slide 23 will be free to return to its rearward position.

It will be evident that the carrier slide 23 constitutes'a receptacle for an article to be vended and that the rod 32 constitutes a member adapted to be locked to said receptacle by a coin, and in some of the claims these parts, namely the carrier slide 23 and the rod 32 are broadly designated by these terms.

It is evident that without departing from the spirit of my invention the coin chute 80 may be omittedand the standard coin when released by the gripping means allowed to drop into a receptacle located in the casing, and in such a case the coin chute 81 would operate to guide the coin when released from the gripping means to the chute 83 as hereinbefore described.

The general operation of the mechanism hereinbefore specifically described is as follows 1. Assuming the partsof the machine to be in their normal and relative positions as illustrated'in the figures of the-drawings and that the user drops a coin of predetermined dimensions, in this particular case, a nickel, into the coin slot 48, said coin will pass downwardly through the coin slot 48 into the coin slot 49 and assume the position illustrated in dotted lines, Fig. 3, and in full lines, Fig. 5. The user of the machine then operatesthe same to pull the crank handle toward the front of the machine. This will operate as hereinbefore described to move the rod 32 and the carrier slide 23 to which said rod is locked by the coin 47 toward the front of the machine. At the same time the end of the lever 50 will be moved out of contact with theear 52 and all parts which are mounted upon the carrier slide will move therewith, and during this forward movement, the lever 66 will be operated by the pin 68 in the slot 69 to draw the link 64; toward the right, Fig- 3, through and by means of the spring 72. This will cause the arms 58 and 59 to be rocked downwardly and thus cause the screws 56 and 57 to be moved toward each other and into contact with the coin 47 with a positively applied yielding pressure. The pin 61 will be moved as hereinbefore described downwardly to clear the tooth 85. and shoulder 86 on the cam plate 75, and as this cam plate which is fast. to the slide ?6 is the member which downwardly and into the receptacle 20. During this forward movement of the slide,

the article 28 is carried forward by the carrier slide pushing the same off of the plate,

90, whereupon it drops to the position illustrated in dotted lines, Fig. 5, onto the stationary plate 106. As'soon as the handle is released, the spring 42 rotates the shaft 38 causing the screws 56 and 57 to 1 release the coin 47 and allow the same to drop into the chute 80' from'which it rolls.

to cause the parts to return to the relative positions illustrated in Fig. 2 and during this return movement the pusher 107 on the carrier slide will push the article 28 oil' of the shelf 106 and the same will drop onto the chute 83 and roll down the same and out onto the shelf 84 where it may be obtained by the operator of the machine. It will be understood that as so-onas the carrier slide starts to move forward as hereinbefore set forth, the flange 25 upon the spring actuated guide member 22 will move forward and engage the article 26 and; hold the same in the position. illustrated in Fig. 5 until the car-' rier slide returns to its normal position and during the last part ofihis return movement, the carrier slide will engage the flange 24,

.and push the guide member'22 and the flange 25 backwardly, thus releasing the article 26 and allowing it to drop into'the space 29 in the carrier slide 23 formerly occupied by the article 28. r i

2. Assuming that no article, such as 28, v

feeds downwardly from the magazine into the space 29 in the carrier slide 23 and that a user of the machine drops a standard coin into the coin slot as hereinbefore described, in such a case the coin will be returned to the user by reason of the fact thatthe feeler finger 92 as soon as the carrier slide 23 moves forward, will be allowed to move toward the right, Fig. 2, by reason of the pin 97 on saidfeeler finger being moved to the position illustrated in dotted lines, Fig. 7, and

this movement will bring the projection 103 on the feeler finger 92 into alignment with the lateral projection 104 on the extension 91 of the slide 70' to which the auxiliary coin chute79 is fastened, then upon further forward movement of the carrier slide, the feeler finger, by means of the projection 103, will engagethe projection 104 and push the slide 76' forwardly so that when the coin drops, instead of dropping into the chute 80 and being conveyed into the receptacle 20, it will fall into the chute 81 and from thence will roll onto the chute 83 and out onto the shelf 84 and the customer will thus receive his money back where he has not received value therefor in theshape of one of said .articles.

3. Assuming that the user of the machine drops a blank, which is notexactlythe same thickness as the coin which it is intended to use in the machin into the slot 48, the machine. will then 'operate as hereinbefore described "to return the coin to the user no articlewill be delivered to him by reason of the fact that the arms 58 and 59 will he depressed enough so that the radial pin 61 will engageE the tooth 85, or the shoulder 86, in either of which cases the cam plate fast to the slide 76 willmove said slide and the auxiliary coin chute thereon so that the forward movement of thp slide, will be dropped into the coin chute 81 and will pass out of the machine by dropping onto the chute 83 and rolling out onto the shelf At the same time the extension 91 to which the plate 90 is fastened will move forwardly and remain beneath the article 26 and prevent its dropping onto the shelf 106 as hereinbefo're described. When the car-' rier slide is allowed to return to its normal position as hereinbefore described, the ar-' ticle 26 will be carried back to its starting position as illustrated in Fig. 5, the article 28 having been held suspended as hereinbefore set forth by the guide member 22 and its vertical flange 25.
